Part I Analysis Questions: 1. When a corn plant with all purple kernels is crossed with a corn plant with all yellow kernels, the offspring have all purple kernels. a. Using your understanding of inheritance, explain this observation / outcome. b. What is the genotype of each of the parents (link to the phenotype) and the purple offspring? c. If the purple offspring was to reproduce, what gametes would it form? 2. What would be the genotype(s) and phenotype(s) of the offspring when a heterozygous corn plant is bred with a homozygous plant with purple kernels? Show your work in a Punnett square and explain why you would get the proposed offspring (demonstrate your understanding of inheritance in terms of genotype and phenotype). 3. What would be the genotype(s) and phenotype(s) of the offspring when a heterozygous corn plant is bred with another heterozygous corn plant? Show your "reasoning" with a Punnett square.

Question
Part I Analysis Questions:
1. When a corn plant with all purple kernels is crossed with a corn plant with all yellow
kernels, the offspring have all purple kernels.
a. Using your understanding of inheritance, explain this observation / outcome.
b. What is the genotype of each of the parents (link to the phenotype) and the
purple offspring?
c. If the purple offspring was to reproduce, what gametes would it form?
2. What would be the genotype(s) and phenotype(s) of the offspring when a
heterozygous corn plant is bred with a homozygous plant with purple kernels? Show
your work in a Punnett square and explain why you would get the proposed offspring
(demonstrate your understanding of inheritance in terms of genotype and phenotype).
3. What would be the genotype(s) and phenotype(s) of the offspring when a
heterozygous corn plant is bred with another heterozygous corn plant? Show your
"reasoning" with a Punnett square.
4. Looking back at your data, what do you predict was
a. the genotype of each parent to produce Corn Ear A? Support your answer with a
written explanation and a Punnett square
b. the genotype of each parent to produce Corn Ear B? Support your answer with a
written explanation and a Punnett square
5. Using the data from either Corn Ear A or Corn Ear B, explain the Law of Segregation,
addressing both parents and their offspring. You need to do this in writing, but can also
add pictures if needed.
